生物大分子国家重点实验室自1990年引进并安装我国第一套X射线面探测仪系统以来,已先后收集了来自中国各实验室的不同生物大分子的X射线单晶衍射数据二十几套,数据的Rsym从2.18％(胰岛素母体)到8.69％(葡萄糖异松酶).中分辨率衍射数据的收集时间一般为24—40 h,充分显示了该套系统速度性,数据质量可靠,节省晶体和自动化程度高等优点.本文在概括介绍面探测仪系统的结构和工作原理的基础上,对数据的质量进行了重点分析,并对原Xengen程序包在处理R3空间群的多解问题及如何选取矩阵参数等进行了详细讨论.
State Key Laboratory of Biological Macromolecules Since the introduction and installation of China’s first X-ray surface detector system in 1990, it has successively collected over 20 sets of X-ray single crystal diffraction data of different biological macromolecules from various laboratories in China. , Rsym data from 2.18% (insulin matrix) to 8.69% (glucosinolate enzyme) .In the middle resolution diffraction data collection time is generally 24-40 h, fully demonstrated the speed of the system, the data quality and reliable, save Crystal and high degree of automation advantages.Based on the general introduction of the structure and working principle of surface detector system, this paper focuses on the quality of data and analyzes the multi-solution of the original Xengen package in dealing with R3 space group and how Select the matrix parameters were discussed in detail.
